When youre on the top of a mountain, the temperature level drops, getting colder, When youre going down temperature rises getting hotter. What do you think of the cause? is it the sun? or is it the earth's core? Some says that the closer we are in the sun the more it becomes hot, some says that the more we are near in this inner core of our planet the more hotter? Me.. I agree with the core. How about you?

It's a mixture of things, the earth radiates heat out, we are closer to the core of the earth than we are to the sun so it is that we feel. It gets colder the higher up we get because the air gets thinner, there is less oxygen so we tire quickly and the muscles aren't getting enough energy to work properly and it is our muscles which generates body heat to keep us warm.
